Abstract (en)
[origin: WO2017080584A1] A quadrature digital power amplifier system (100) and a method (200) for converting an IQ data signal (IQ) to an RF signal is described. The method comprises the steps of receiving (202) an IQ data signal (IQ), decomposing (204) the IQ data signal (IQ) into at least a first IQ data subsignal (IQ1) and a second IQ data subsignal (IQ2) if the signal level of the IQ data signal (IQ) in a given sample is above a first threshold level, converting (206) the first IQ data subsignal (IQ1) to a first RF signal, and converting (208) the second IQ data subsignal (IQ2) to a second RF signal. The quadrature digital power amplifier system is configured to perform such a method. A transmitter device (300) for a wireless communication system (400) comprising such a quadrature digital power amplifier system is also described.
